Replacing the System and Backplane Board Assemblies 3

The system board and backplane board are removed from the chassis as a single assembly, and are

then separated for replacement of either board.

Removing the System Board/Backplane Board Assembly

CAUTION: See your System Information Guide for complete information about safety precautions,

working inside the computer, and protecting against electrostatic discharge.

NOTE: It is not necessary to remove the hard drives or the CD/diskette drive from the system during this

procedure.

To remove the system board/backplane board assembly, perform the following steps:

Turn off the system and attached peripherals, and disconnect the system from the electrical

outlet.

Open the system. See "Opening the System" in your

Installation and Troubleshooting Guide

If you are replacing the system board, remove the system battery. See "Replacing the Battery"

in your

Installation and Troubleshooting Guide

If you are replacing the system board, remove the heat sink and processor. See "Replacing the

Processor" in your

Installation and Troubleshooting Guide

If you are replacing the system board, remove the memory modules. See "Removing Memory

Modules" in your

Installation and Troubleshooting Guide

Remove the cooling shrouds.

Disconnect the control panel cable from the J3 connector on the backplane board. See

"Removing the Control Panel Assembly" in your

Installation and Troubleshooting Guide

Disconnect the power and interface cables on both hard drives from the backplane board

(connectors JP1, JP2, IDE0 and IDE1).

Disconnect the power supply cable from the back of the backplane board (connector J2). See

"Replacing the Power Supply" in your

Installation and Troubleshooting Guide

If the hard-drive interface cables are routed through the backplane to a PCI controller card,

disconnect these interface cables from the PCI controller card.

Remove all PCI expansion cards installed on the riser board. See "Removing an Expansion

Pull the backplane board away from the system board. See Figure 1-2.

Installing the System/Backplane Board Assembly

CAUTION: See your System Information Guide for complete information about safety precautions,

working inside the computer, and protecting against electrostatic discharge.

NOTE: It is not necessary to remove the hard drives or the CD/diskette drive from the system during this

procedure.

To install the system board/backplane board assembly, perform the following steps:

Connect the four-conductor power cable to the back of the backplane (connector U3). Secure

this connector with a plastic cable tie to the backplane.

Connect the system board to the backplane board. See Figure 1-2.

NOTICE: Use a screw only in the center screw hole to secure the system board/backplane board to the

chassis.
